  1. Radar and EW Knowledge Base27 November 2008 Presented by Brian FERGUSON Tellumat Defence Marketing & Sales Manager

  2. Introduction to Tellumat Defence • Electronics & Precision Mechanical Company • Private, 100% South African • Based in Cape Town, Offices in Pta and Jnb • Design, Manufacture, Supply, Support • Wide and High Technology Base • Broad and Deep Industrial Base • Independent from Multi-Nationals • Develop Alliances and Partnerships

  3. Tellumat Business Activities • Telecoms • Wireless Radio Solutions • Contract Manufacturing • Defence – Radar • Defence – Navigation Systems • Defence – Communication Systems • Defence – Identification and Data Link Systems • Defence – Mechanical Artillery Fuzes & Safe-and-Arm Devices

  4. Technology Development Objectives • Develop technologies, systems and products • Develop re-usable building blocks and technology elements to form the basis of families of systems and products • Joint development programmes between Tellumat and development partners • Minimise time to market for the systems and products • Minimise technical and schedule risk by following an iterative development approach

  5. Technology Development Process

  6. Technologies in Tellumat • DSP Processing from IF (Sub Nyquist Sampling) • Simulation with “Hardware-in-the-Loop” • Selected elements of SDR (Software Defined Radio) • UML for software design / documentation • SysML for system engineering • RTOS Real Time Operating System (VXWorks) • Software designed to international certification requirements (RTCA DO-178B, 278 etc) • Combination of proprietary and OEM (Open Standard) hardware

  7. Technologies in Tellumat • 3-D modelling of mechanical elements • Thermal analysis / cooling design using finite element analysis • Electronically steerable antenna arrays • Micro-strip / micro-wave design using simulation tools (ADS - Advanced Design System) • High powered solid state pulsed amplifiers • Monopulse processing / tracking • Cryptographic software and hardware

  8. Primary Radar Activities • AR3D Long Range Air Defence Radars – Support and Upgrade • AFRAS Airfield and Precision Approach Radars – Support

  9. AR3D Upgrade Details • Antenna • Total refurbishment and overhaul • Automatic temperature / pressure sensing • Transmitter • Complete refurbishment and overhaul • New digital sweeper • New technology oscillating circuitry • Enhancements to power generation system • Stability improvements • New secure pulse pattern (ECCM)

  10. AR3D Upgrade Details • Signal Processing • New receivers • New MTI (moving target indicator) • Clutter map • Radar Control • New radar processor • Improved HMI (human machine interface) • BITE (Built-In Test Equipment) • New improved BITE • Processor and Displays • New generation COTS technology • New generation scan conversion technology

  11. AR3D Upgrade Details • Operational Software • Proven flexible Windows based system • Latest air space control functions • Plot integration flexibility • Software is adaptable (easy to change) • On-line diagnostics • Tech Mon Upgrade
